Abstract

A method for connecting two components. The method includes heating a deformation region of at least one component part to provide complete heating. The at least one component part is plastically deformed after the complete heating of the deformation region.

First claim

The invention claimed is:

1. A method for joining two components by plastic deformation, the method comprising the steps of:
simultaneously heating a plurality of different axially spaced deformation ranges of at least one component by radiation including a laser for heating an entire circumference of the at least one component, the deformation ranges comprising two deformation areas; and
plastically deforming the at least one component part after simultaneously heating the plurality of axially spaced deformation ranges such that the deformation areas protrude radially outward from the least one component, wherein another component is sandwiched between the two deformation areas.

2. A method according to claim 1 , wherein the plastic deformation occurs in a heated state.

3. A method according to claim 1 , wherein the deformation area is cooled down prior to the plastic deformation.

4. A method according to claim 1 , wherein the structure of the at least one component is locally weakened by the heating.

5. A method according to claim 1 , wherein the two component parts are bonded to one another by crimping, the deformation areas being in direct contact with the another component.

6. A method according to claim 1 , wherein the two components are metallic component parts that are joined to one another.

7. A method according to claim 1 , wherein radiation is a ring-shaped radiation diverted via an optical means.

8. A method according to claim 1 , wherein the heated component part, after bonding with another component part, is cooled in such a way, that subsequently the heated component part has the desired material properties.

9. A method for joining two components by plastic deformation, the method comprising the steps of:
simultaneously heating a plurality of axial extents of at least one component by radiation to provide a plurality of heated of axial extents, each of said axial extents being located at a spaced location from each other, wherein a non-radiated area of the at least one component extends between each of said axial extents and another one of said axial extents; and
subsequent to initiating said radiation, plastically deforming the at least one component part such that each of said heated axial extents extends radially outward from the least one component to form plastically deformed areas of said at least one component, wherein another component is fixed via said plastically deformed areas of said at least one component, said another component being located opposite at least a portion of said non-radiated area.

10. A method according to claim 9 , wherein the plastic deformation occurs in a heated state.

11. A method according to claim 9 , wherein the deformation area is cooled down prior to the plastic deformation.

12. A method according to claim 9 , wherein the structure of the at least one component is locally weakened by the heating.

13. A method according to claim 9 , wherein the two component parts are bonded to one another by crimping, said another component being in direct contact with said plastically deformed areas.

14. A method according to claim 9 , wherein the two components are metallic component parts that are joined to one another.

15. A method according to claim 9 , wherein the radiation is a ring-shaped radiation diverted via an optical means.

16. A method according to claim 9 , wherein the heated component, after fixing to the another component, is cooled in such a way, that subsequently the heated component part has desired material properties.

17. A method for joining two components by plastic deformation, the method comprising the steps of:
providing at least a first component, said first component comprising a first area and a second area, said first area being located at a spaced location from said second area;
providing at least a second component;
simultaneously heating said first area and said second area by radiation to provide a plurality of heated areas, said first component comprising a non-radiated area extending between said first area and said second area; and
subsequent to initiating said radiation, arranging said second component adjacent to said first component and plastically deforming the first component such that each of said first area and said second area extends radially outward from the first component to form at least a first plastically deformed area and a second plastically deformed area of said first component, wherein said second component is fixed to said first component via said first plastically deformed area and said second plastically deformed area, said second component being located opposite at least a portion of said non-radiated area.

18. A method according to claim 17 , wherein the plastic deformation occurs in a heated state.

19. A method according to claim 17 , wherein the first area and the second area are cooled down prior to the plastic deformation.

20. A method according to claim 17 , wherein the radiation is a ring-shaped radiation diverted via an optical means, said second component being in direct contact with said first plastically deformed area and said second plastically deformed area.
